Overview
On August 6 and 9, 1945, the United States dropped atomic bombs on the Japanese cities of Hiroshima and Nagasaki. 'Little Boy' killed 70,000–80,000 immediately in Hiroshima; 'Fat Man' killed 40,000–50,000 in Nagasaki. Total deaths including radiation exposure reached 110,000–210,000. These remain the only uses of nuclear weapons in armed conflict in history and prompted Japan's surrender, ending WWII.
